Student should be able to:
- Apply use of quadratic equation box in expanding and factorizing algebraic expressions.
- Solve quantitative reasoning problem
Expansions Leading to Quadratic Expressions
A quadratic expression is one in which 2 is the highest power of the unknown(s) in the expression. For example, x2 – 4x – 12, 16 – a2, 3x2 + 17xy + 10y2 are all quadratic expressions.
Expand: (a) (a + 3) (a – 4)
(b) (2x + 3) (4x – 5)
- (a + 3) (a – 4)
=a (a –.... View More
